IPC: A63F7/02
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To prevent looseness and a flaw by stably holding a rotary operation member in an optional rotary degree by a procedure familiar with a game player.

IPC: B41J11/00
Filed: 1993-02-24
Abstract: PURPOSE:To suppress the positional shift and to prevent color shift by preventing the slip of a platen roller and a feed roller at low cost by a simple structure without scaling up a color thermal printer. CONSTITUTION:Both side end roller parts 12 with which the side end edges 3a of paper 3 come into contact of a platen roller 10 are formed from a non- elastic member and have rough surfaces while the pressure roller parts 22 pressed to the side end roller parts 12 are provided to a feed roller 20 and, when the paper 3 is printed, the platen roller 10 is reversibly rotated to reciprocally move the paper 3. At this time, the rotary error caused by the depression due to elasticity generated in an elastic member is not generated in the side end roller parts 12 and the transmission of rotation to the pressure roller parts 22 is surely performed and the transmission accuracy of rotation is enhanced. Therefore, the slip of the pressure roller parts 22 becomes hard to generate and the coefficient of friction with the paper 3 becomes large and the side end edges 3a of the paper 3 are surely fed without generating a slip and the positional shift of the paper 3 is prevented.

IPC: H05B6/06
Filed: 1990-02-15
Abstract: PURPOSE:To reduce current flowing in an adjacent heating coil, a resonance capacitor serially connected to the coil and an element connected to the adjacent coil by regenerating, to a DC power source, induced electromotive force which is generated when a magnetic flux generated from a heating coil to which high frequency current is supplied functions the adjacent heating coil. CONSTITUTION:Winding directions of a plurality of heating coils 50, 52 which are adjacent to each other are made reverse to each other. A first heating coil 50 is connected to a lower potential side switching element 7 which is turned on by a control circuit 16, and a magnetic flux generated by a high frequency current supplied to the heating coil 50 functions to an adjacent second heating coil 52. Induced electromotive force generated on the heating coil 52 is regenerated to a DC power source 1 since the winding direction of the coil is reverse to that of the heating coil 50. Thus it is possible to suppress current flowing in the heating coils 50, 52, resonance capacitors 11, 14 serially connected to the coils, higher potential side switching elements 6, 8 and lower potential side switching elements 7, 9.
